Banknote Stacking Apparatus with Damper and Sensor Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional banknote stacking apparatuses face challenges in stably stacking banknotes due to deformation and blowing away, especially when dealing with various types and sizes of banknotes, as existing solutions fail to effectively prevent banknotes from being blown away and do not adequately adjust the push plate movement according to the number of stacked banknotes.
Innovation Solution
A banknote stacking apparatus featuring a stacker with a damper and push plate system, where a damper is used to press banknotes toward a push plate, preventing them from being blown away, and a controller adjusts the push plate's movement based on sensors detecting the number of stacked banknotes, ensuring stable stacking by temporarily holding banknotes and expanding the stacking space as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If elastic sheets hit banknotes in an upwardly inclined direction to stack them, then banknotes are stacked toward the push plate, but banknotes are blown away and deformed making neat stacking difficult
Solution Approach 1:
The stack guide is positioned to guide banknotes into the stacking space before the elastic sheets make contact. This preliminary guidance ensures banknotes are properly oriented and positioned, preventing them from being blown away or deformed when hit by the elastic sheets, thus resolving the contradiction between stacking speed and alignment precision
Solution Approach 2:
The stack guide acts as an intermediary element between the banknote feed and the elastic sheet impact point. It mediates the banknote's entry into the stacking space, controlling its trajectory and position, which prevents the harmful effects of direct impact while maintaining efficient stacking
2Reliability
If a fixed stopper is provided at the upper portion of the stacking space, then some protection against blown away banknotes is provided, but small banknotes cannot be effectively prevented from being blown away in a large stacking space
Solution Approach 1:
The stack guide is designed to be movable rather than fixed, allowing it to adapt its position based on the size of the banknotes being stacked. This dynamic adjustment capability enables effective guidance and protection for both small and large banknotes, resolving the contradiction between reliability and adaptability
Solution Approach 2:
The system changes the positional parameter of the stack guide dynamically to accommodate different banknote sizes. By adjusting the guide's position, the effective stacking space and guidance geometry are modified to suit various banknote dimensions, providing consistent protection against being blown away
3Productivity
If the push plate moves a predetermined distance to make space for new banknotes, then stacking continues, but abnormal banknotes cause insufficient free space and smooth stacking cannot be maintained
Solution Approach 1:
A sensor detects the position of the stack guide and provides feedback to the controller. Based on this feedback, the controller adjusts the push plate's movement distance dynamically, ensuring that sufficient free space is always maintained regardless of whether banknotes are stacked normally or abnormally, thus maintaining stacking smoothness and continuous operation

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The apparatus effectively prevents banknotes from being blown away and improves stacking quality by ensuring that banknotes are stably aligned and securely held, even when different types and sizes are stacked, by using sensors to control the damper and push plate movement.
Implementation Method 1
the rear end of the banknote P introduced into the one side of the banknote stacking space 30 is hit by the rotating elastic sheet 23a of the stack roller 23 and stacked in a direction toward the push plate 40
Implementation Method 2
a damper configured to press the banknote introduced into one side of the banknote stacking space toward the push plate located on the other side of the banknote stacking space and prevent the banknote from being blown away
